Container with Air Intakes

ABSTRACT

A container including a vessel, a top plate, a first hole, and one or more second holes is provided. The vessel is for storing liquid, and includes open top and closed bottom portions. The first hole on the top plate has a first open state and a second close state, and the first hole allows the liquid to flow through the first hole in the first open state. Each of the second holes on the top plate includes a first open state and a second close state. When at least one of the second holes in the first open state allows air traffics between inside and outside. At least one of the second holes allows air flow through the second hole so as to equalize air pressure of the inside and outside of the container when the liquid flows through the first hole.

BACKGROUND OF THE INVENTION

The present invention relates to a container with air intakes.

More particularly, this invention relates to a container with air intakes to equalize air pressure inside and outside of the container.

Soft drink or beverage has been packaged in a paper pack, which has a hole for a straw.

When a user drinks from such a pack, the pressure inside the pack decreases as more and more liquid are sucked out through the straw. Therefore, it gets harder and harder to drink as the pressure difference becomes larger. This low pressure inside and high ambient pressure outside is caused because the straw fits tight against the rim of the hole leaving almost no space through which the air flows in and out. For the same reason, the liquid squirts out easily when the pack is squeezed even slightly.

These problems are clear to see from a paper pack 1 of a prior art as shown in FIG. 1. A straw 4 is held tightly in a hole 3 provided on the paper pack 1. There is no path for air flow easing out the pressure building across walls of the paper pack 1.

Accordingly, a need for a container with air intakes has been present for a long time considering the range of use along with a straw. This invention is directed to solve the problems and satisfy the long-felt need.

SUMMARY OF THE INVENTION

The present invention contrives to solve the disadvantages of the prior art.

An object of the invention is to provide a container which does not overflows through a straw when squeezed.

Another object of the invention is to provide a container which ease out the air pressure difference between the inside and outside of the container.

DETAILED DESCRIPTION OF THE INVENTION

An aspect of the invention provides a container 100 for storing and suckling liquid.

The container 100 comprises a vessel 10, a top plate 20, a first hole 30, and one or more second holes 40.

The vessel 10 is configured to store liquid, and comprises an open top portion and a closed bottom portion.

The top plate 20 is configured to close and seal the open top portion of the vessel 10.

The first hole 30 is provided on the top plate 20. The first hole 30 comprises a first open state and a second close state, and the first hole 30 is configured to allow the liquid to flow through the first hole 30 in the first open state. The first hole 30 is configured to keep the liquid from leaking through the first hole 30 in the second close state.

The one or more second holes 40 are provided on the top plate 20, each of the one or more second holes 40 comprises a first open state and a second close state. When at least one of the one more second holes 40 is in the first open state the opened second hole 40 is configured to allow air traffics between inside and outside of the container 100, and when all of the one or more second holes 40 are in the second close state the second holes 40 block flowing of the air through the second holes 40.

At least one of the one or more second holes 40 allows air flow through the second hole 40 so as to equalize air pressure of the inside and outside of the container 100 when the liquid flows through the first hole 30.

The top plate 20 may be integrated with the vessel 10 to form a monolith except for the holes 30, 40.

The first hole 30 may be covered by a pokable membrane. The pokable membrane may be configured to be broken by poking with a straw 90, and the size of the first hole 30 may be determined by the size of the straw 90.

The first hole 30 may be substantially circular in cross-section just as the shape of the straw 90. In certain embodiments, the shape of the first hole 30 does not correspond to the shape of the straw 90.

At least one of the one or more second holes 40 may be covered by a pokable membrane, and the pokable membrane may be configured to be broken by poking with a straw 90.

The size of the second hole 40 may be smaller than the size of the first hole 30. The second hole 40 may be small enough to keep the liquid from flowing with surface tension of the liquid at the second hole 40. Still, the small second hole 40 can allow air to flow in from outside when the liquid inside is sucked out. The pressure difference pushes out the liquid drop blocking the second hole 40 and leads in air from the outside.

In certain embodiments shown in FIG. 6, at least one of the one or more second holes 40 may be blocked with a plug 50. The plug 52 may be connected to the top plate 20. The plug 52 may be configured to close the second hole 40 when pushed in and open when plucked out. The plug 50 may comprise a head 52 and a stem 54 extended from the head 52, and the stem 54 may comprise a leaking hole 56 leading from a bottom of the stem 54 to a side wall of the stem 54 such that the leaking hole 56 is exposed and opens to the outside when plucked out by a predetermined length.

In certain embodiments shown in FIG. 7, the second hole 40 may be blocked by a sticky membrane, and the sticky membrane may be configured to be opened and closed repeatedly. An edge of the sticky membrane may be fixed to the top plate 20.

Another aspect of the invention provides a container which is not of a shape of box. The container may look like a bloated envelope or sack as shown in FIG. 8. The air intakes, the second holes 40, can be provided on a top or middle portion of the container 100.

With the air intakes, the container is easily crushed when discarded after use.
